What Domain Info Helper does

local-first

Domain Info Helper extracts domains and HTTP(S) URLs from pasted lists or mixed text, normalizes paths and ports, marks invalid and duplicate rows, and exports unique results as TXT or CSV. Select any valid domain to prepare its copyable DNS and WHOIS audit checklist without a network lookup.
